Which would be fine if my windows explorer wasn't showing that it mounts, as well as allowing me to actually look inside the various folders and subfolders of the nook, I've been using calibre between a ubuntu laptop rig and a windows home machine for about 3 years now as it's the most convenient management tool for my ereader:

In addition I ran all this in debug mode, so if wanted I could share the following text I got from that as well. I promise that this isn't a "newbie forgot to plug it into the micro-usb" issue, I lurked pretty extensively before even signing up for the forum because I figured there *had* to be some kind of fix already present. I checked the default plug-ins and they're all enabled, are there third party plugins that might fix this issue?
